As the temps change, the more you feel the colder air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Lafayette home, it’s time to reach out to AC Sales. Once in a while a lack of warm air from your gas furnace results in a big repair, but often it can be an easy fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had ongoing maintenance done on your gas furnace for some time and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace might overheat and shut down its burner.
Your pilot light may have gone out
Sometimes a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a draft to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in challenges for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and reduce the warmth inside your house.
Your ducts may not be properly sealed
If your ducts aren’t properly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it can get to the vents.
